Forge is one of Regent's signature combat hooks. The first Forge card each combat creates Sovereign Blade, and later Forge stacks make that blade hit harder.
Forge is not a generic crafting system. In Mega Crit's public reveal, it is a combat keyword tied to Regent and to the created card Sovereign Blade.
The rule that matters most is simple: the first time you play a card with Forge each combat, the matching Sovereign Blade is created in your hand. Every later point of Forge increases how much damage that Blade will deal.
Verification note
Based on Mega Crit's December 11, 2025 Regent reveal. The public description focuses on Regent's interaction with Sovereign Blade.
Why Forge matters
If you are seeing Forge for the first time, start with the rule. That is the fastest way to make sense of the fights, cards, and choices built around it.
Once the basic rule clicks, the related links show you where Forge starts changing real decisions in a run.
Learn the rule before you worry about ranking or build theory.
Open the related guides if Forge changes pathing, card picks, or early-act risk.
Come back after major updates if wording, balance, or examples change.
Forge asks a different question from most obvious attack keywords. It is not about the printed card alone; it is about the delayed payoff it enables later in the combat through Sovereign Blade.
That makes Forge easier to misplay than it first appears. A player who treats it like free immediate value can miss the fact that the real payoff lives in the created Blade and in how much later Forge scaling you feed into it.
Regent's reveal pairs Forge with Stars for a reason. Stars let you bank a resource over time, while Forge lets you invest into a later combat payoff. Together they create a class that thinks in setups and spikes rather than in single-turn efficiency only.
That is also why a Regent guide works better when it links directly to Stars and Forge instead of trying to explain the whole class in one undifferentiated page.
Explain the creation rule first, then the scaling rule, then show a real example once you have a verified Regent card list. Players do not need lore first. They need to know why Forge changes their turn planning.
Comparison
Forge matters because it turns a familiar concept, making cards better, into a class-facing keyword rather than only a campfire decision or one-off effect.
Slay the Spire 1
Upgrading cards was most often anchored to smithing, relics, and scattered card effects.
Slay the Spire 2
Forge is part of Regent's actual class identity and preview trail.
Why it matters
The sequel gives upgrade-like improvement a more visible class vocabulary.
Slay the Spire 1
Improving cards was important, but it did not usually define an entire launch class.
Slay the Spire 2
Forge helps define what Regent is trying to do in a run.
Why it matters
It makes a familiar improvement idea feel like a core strategic identity instead of a background system.

FAQ
The official wording says the first time you play a card with Forge each combat, the corresponding Sovereign Blade is created in your hand.
Mega Crit says later Forge stacks increase how much damage Sovereign Blade will deal.
That is how Mega Crit has publicly presented it. Until the live card pool shows a broader use, Regent is the correct home for Forge coverage.
